SHIPPING- A'ITACHMENT FOR 'WEIGHZNG SGALES.

Application filed August 1, 1925.

This invention is directed to improvements in devices and a achmen for use in connection with weighn M cales and more particularly with the scales of the ty* shown in my copending applica i No. 4.74. 2, filed lingust l, 1975. ticnlarly the dc iccs and at nents are in tended for application to g: scales to hold various parts thereof rn'ily in position and to prevent damage to these and other parts when shipping the scales.

The invention further has for objects the provision of devices which may readily be applied at the factory and which also may be readily removed by a comparatively inexperienced person.

Further objects and advantages will he hereinafter set forth in the accompanying specification and claims and shown in the drawings which by way of illustration show preferred embodiments of my invention.

In the drawings:

Fig. 1 shows a perspective view of a scale with the devices and attachments applied thereto and the scale in condition for shipment.

Fi 2 is a side elevational view of a s ale with the improvements applied thereto. Certain parts are shown broken away and in section to show the interior construction.

Fig. 3 is a top plan. view of the base lever system of a scale with my improved shipping spider applied thereto.

Fig. at is a detail View taken on line 4.L of Fig. 3.

Fig. 5 is aside detail view taken on line 55 of Fig. o.

Fig. 6 is a detail part sectional view taken on line 66 of Fig. 3.

Fig. 7 is a further detail sectional view taken on line 7-7 of Fig. 3.

Referring now to the drawings, 10 is the base casting of the scale having a fulcrum stand 11 which supports the fulcrum pivots 12 of lever 13 in the usual manner. 1+2 de nates the load pivots of the scale which support the bearing frame 15 in the usual man ner. 16 is the steelyard which, as shown in Fig. 2, is disconnected from the indicator and load count-erbalancing operating connection generally designated 1.? As shown in this figure, the steelyard 16 is tied by a cord 18 to the operating connection 17 and to one of the shipping bracket members 32 which will subsequently be described.

Serial No. MAM.

In preparing" a smile for vision should be made for mg the main cale lever out of its cooperating bearings ard further provision should be made for lifting the bearing frame out of cooperation with the load pivots. Also in weighing scales of this type the indicator and load counterbalancing operating connection member 17 has co; is ted to its c.p=ali;:er parts, racks and load counterbalancing springs. Provision should be uade for preventing these parts shift. ahout during shipment of the scale. The means for securing these results will now be described. p

Referring to Figs. 3 and 2. the base cover, not shown, the platform and like parts are first removed. A shipping spider generally designated. 20 is then placed in position upon the top of the base cover. This shipping spider preferably is in the form of a 05am;- having dependingfoot portions 21., 22 and 23. These. foot portions are slmuldered as shown at 24 (F 3 and l) to loosely lit inside the base housing. Before placing the spider in position the base housing is covered with a suitable cushioning material such as a piece of felt so. Thereafter screw studs 27 are tightened, drawing the spider tightly down into contact with the felt pads 26. Screws 27 preferably take into the pedestal-like bosses 28 which are integral with and a part of the base casting l0. Screws or studs 27 preferably eiitcnd through slots 30 in the spider 20 so that the screws may properly adjust themselvesirrespective of slight irregularities of the base parts of the scale.

After the spider in position a resilient metal strap member 32, Fig. 2, is secured to the operating connection 17 by means of a screw 83 which passes through an elongated slot in member 32. A suitable cushion or pad 83 is placed between the member and the column housing of the scale, and the slotted lower end of the member is fitted under a stud 34:, see Fig. 6. A. suitable block of wood 35, preferably drilled. or slotted to allow the stud 3-l to pass therethrough, is placed between member 20 and the bosses 36 on the main scale lever 13. A similar wooden block 37 is placed under the forward end of the shipping spider and intermediate it and the forward end of the lever 20. Studs 38 pass through suitable slots39 in the forward ends of the shipping spider, and

'pment prothese studs, as well as stud 34;, which passes through a slot 11 in the spider 20, are then tightened up to draw the lever 13 vertically upward and to lift the fulcrum pivots 12 of the lever out of cooperation with the bearings. The various studs are tightened to firmly clamp the lever assembly to the shipping spider. lVith the parts in this position strap 32 acts to firmly but resiliently secure the movable operating connection 17 against displacement.

'The bearing frame may be lifted up and removed from cooperation with the load pivots 14.- in a similar manner. Preterably this is brought abort by tightening up on screws 40, Figs. 3 and 4t. These screws 4C0 {it into threaded sockets in the bearing frame 15 as clearly shown in Fig. 4;. Suitable wooden cushioning blocks 12 are also interposed between the bearing frame 15 and the spider 20. The scale is now in condition for shipment, and all movable parts are firmly secured against accidental displacement.

The slots 39, and L1 permit the various lever and bearing frame parts to be raised freely and withoutbinding or stressing the same. The studs adjust their positions as required by the position and configuration ot' the parts. The wooden blocks 37, and s2- serve as cushion members which prevent shocks. which occur during shipping of the scale from shearing oil the various studs. A slight shittot the parts can take place without, however, excessive movement thereof. l urthermore the bearing frame itself can slightly shift and adjust itself to base covers of slightly different size or configuration.

I claim:

1. A shipping attachment for a weighing scale having a base lever system and a displaceable operating connection to the weight indicator and load counterlnilancing means comprising a spider device adapted for cooperation with fixed parts of the scale with provisions for holding the base lever system against movement when shipping the scale, and means associated with said spider and arranged for connection to the aforesaid operating connection for securing the operating connection and its associated parts against movement when the scale is shipped.

2. In a weighing scale having a displace able operating connection associated with the weight indicator and load counterbalancing device. and removal'ile resilient means adapted for connection with said operating connection and with relatively fixed means for preventing displacement of said operating connection and its associated parts when the scale is shipped, the resiliency of said means preventing damage to movable parts upon the scale receiving shocks in shipment.

A weighing scale having a bearing frame and a main scale lever, a base housing, a shipping spider supported thereon. means for drawing up the bearing frame and main lever to a position in which they are supported by the shipping spider and cushioning blocks interposed between the shipping spider and the lever and bearing frame for the purpose described.

4. In a weighing scale provided with the usual bearing frame and lever and having a shipping spider supported upon a base housing, said shipping spider having elongated slots through which studs are adapted to pass and studs passing through said slots for drawing up the bearing frame and lever, said slots permitting relative adjustment of said studs with respect to the shipping spider.

5. In a weighing scale having a weight lever and cooperating bearings, a shipping spider for supporting said lever out of its bearings during shipment and cushioning blocks interposed between said lever and said shipping spider tor cushioning shocks received in shipment. 1

In testimony whereof I hereto atlix my signature.

THOMAS H. STRACHAN.
